There are two ways to do encryption: only your home directory, or the whole physical drive. I always do whole drive encryption.

I think the graphical installer only encrypts the home directories. The alternate installer (ncurses) can do whole disk encryption. Here is a tutorial that documents how I remember the process goes:

Page 3 has a good screenshot of how it should look when it asks for your passphrase during bootup (text-only).

Adding encryption after the installation isn't very difficult. I used this guide last time I did it (start with step 4):

(BTW, Linux Mint Debian Edition is a very nice distribution.)

Good luck,
